Award-Winning Construction Projects

Project

Downtown Sewer Replacement Project
City of Yuba City, California

West Yost designed the relocation, replacement, and/or rehabilitation of existing sewers in the City’s downtown residential area to address structural deficiencies, maintenance issues, and system reliability. The existing sewers were installed nearly 100 years ago and could not be cleaned or maintained due to pipe fragility and lack of access. The challenges of replacing these backyard sewers included access, public outreach, homeowner coordination, design approach, and construction methods for rerouting sewer laterals.
